Abstract
The utility model belongs to the field of a measuring tool of a multi-head screw thread work piece. The multi-head screw thread detecting gauge is characterized by comprising a cylindrical screw thread gauge body for measuring the inner screw thread of a lens cone, and a toroidal screw thread gauge body for measuring the outer screw thread of the lens cone, wherein the outer circle of the cylindrical screw thread gauge body is provided with at least one anticlockwise multi-head spiral lines B, and inner circle of the toroidal screw thread gauge body is provided with at least one anticlockwise multi-head spiral lines A. Compared with the prior art, the detecting gauge has the benefits of being capable of conveniently, fast and exactly detecting the precision of the screw thread of the zoom lens cone, improving the manufacture efficiency of the zoom lens cone, and reducing the cost.
Description
Technical field
The utility model belongs to processing component measuring instrument field; Multi-step thread workpiece calibration field of tool particularly.
Background technology
The zoom lens barrel is the critical piece of camera, monitor, and the precision of zoom lens barrel directly influences the zooming range of camera lens and becomes the sharpness of phase.It is the abnormal screw thread of 36mm that one group of left-handed, 24, helical pitch are arranged on its zoom lens barrel, realize the zoom of camera lens by this screw thread left rotation and right rotation, the quality of fit design of this screw thread is gone up and is required in the 0.02mm, if flute profile angle, helical pitch, a number, dimensional accuracy and roughness have one not up to standard, all be difficult to guarantee its quality of fit, so the multi-step thread accuracy detection of zoom lens barrel just seems particularly important.It is by manufacturing (promptly that zoom lens barrel originally detects, earlier a workpiece processing is finished, the processing of the screw thread of another workpiece and ready-made workpiece threaded engagement) guarantee its quality of fit, but the method is not suitable for producing in batches, and counterpart weares and teares easily, waste a large amount of time, therefore simultaneously a lot of defective productss produces.
The utility model content
The utility model is intended to overcome the deficiencies in the prior art, and providing a kind of can make things convenient for, and is quick, exactly the zoom lens barrel carried out the multi-step thread detection rule of fast detecting.
The purpose of this utility model is achieved in that multi-step thread detects rule, it is characterized in that, comprise the cylindrical thread gauge that is used to measure the lens barrel internal thread, with be used to measure the externally threaded annular thread profile gauge of lens barrel body, at the cylindrical of cylindrical thread gauge one or more anticlockwise multi-head spiral line B that distributing, one or more anticlockwise multi-head spiral line A is distributing on the interior circle of annular multi-step thread gauge.
Described multi-head spiral line B has 24; Described multi-head spiral line A has 24.
Described multi-head spiral line B is a projection (pin thread); Be used to measure the helix groove on the zoom lens barrel cylindrical.
Described multi-head spiral line is groove (female screw), is used to measure the helix projection on the circle in the zoom lens barrel.
Described annular thread profile gauge body comprises two, is respectively drift A and no-go gage A.Described drift A is identical with no-go gage A shape, but the diameter of drift A is more bigger than no-go gage A.
Described cylindrical thread gauge comprises two, is respectively drift B and no-go gage B.Described drift B is identical with no-go gage B shape, but drift B is more smaller than the diameter of no-go gage B.
Compared with prior art, the beneficial effects of the utility model are: detect the precision of advising with this multi-step thread and detect zoom lens barrel screw thread, and convenient, quick, accurately, improved the production efficiency of zoom lens barrel, reduced cost.

Embodiment
Below in conjunction with accompanying drawing, the utility model is further described:
Referring to accompanying drawing 1, accompanying drawing 2: the utility model annular thread profile gauge body construction synoptic diagram, this body is that the annular of a hollow is (because the external form of drift, no-go gage body is identical, so not signal respectively), in annular thread profile gauge body 2, be uniform-distribution with 24 anticlockwise multi-step thread line A1, (described helix is anticlockwise groove female screw) on the circle.Described annular thread profile gauge body has two, is respectively drift and no-go gage, and the external form of logical no-go gage body is identical, and difference only is that the middle footpath size of screw thread differs 0.02mm, and that big is drift A, and that little is no-go gage A.During use, with of drift, the no-go gage respectively mutually examination of external thread workpiece with annular thread profile gauge body, if drift can be twisted to such an extent that enter, and very sliding fast, and no-go gage can not be screwed into, then this workpiece screw thread is qualified; Otherwise be defective.
Accompanying drawing 3 is the utility model cylindrical thread gauge structural representation, cylindrical by the ladder that two cylinders are formed (because the profile of drift, no-go gage body is identical, so not signal respectively), 24 the anticlockwise multi-step thread line B11 that on the great circle of its cylindrical, distributing uniformly, (described helix be counterclockwise the pin thread of projection); Described annular thread profile gauge body has two, is respectively drift B and no-go gage B, and the profile of drift B, no-go gage B body is identical, and difference only is that the middle footpath size of screw thread differs 0.02mm, and little is drift, and big is no-go gage.During use, with of drift B and the no-go gage B respectively mutually examination of internal thread workpiece with the cylindrical thread gauge, if drift B can twist to such an extent that enter, and very sliding fast, no-go gage B can not be screwed into, and then this workpiece screw thread is qualified; Otherwise be defective.
